A plea for the T2W MR sequence for pituitary imaging

To the Editor,
I am frequently called upon as a reviewer by endocrinology journals due to my experience in pituitary magnetic resonance (MR) image interpretation . I feel compelled to highlight some continuing problems in image choice and quality that severely limits scientific analyses, despite the significant technological advances over the past decade. The principal problem- as I see it- is that at the sellar level, almost all images selected for figures are T1-weighted (T1W) images with gadolinium infusion, while T2-weighted (T2W) images are almost always absent. The performance of T2W MR has been improved enormously, particularly at 3.0 T, but also at 1.5 T. T2W images, if optimized, are frequently more informative and gadolinium enhanced T1W images can be spared in some conditions.
In contrast to the general rules for brain MR imaging, i.e. the use of a large number of sequences, pituitary gland MRI protocols need to be adapted to the clinical situation and a limited number of...
